the longer hairs of the elytra inclined but coarse and distinct. 

 Head finely but rather closely punctate, the eyes large and con- 

 vex. Prothorax narrower than the head, of tlie usual form but 

 with the base distinctly narrower than the maximum width, the 

 punctures of different sizes, rounded, dense but not polygonally 

 crowded. Elytra three-fourths longer tlian wide, only very 

 slightly more than twice as wide as the prothorax, parallel and 

 slightly rounded at the sides, evenly and not ver}- broadly round- 

 ed at apex ; humeri not very widely rounded to the prothorax ; 

 oraoplates feeble ; punctures moderately coarse and sparse. Ab- 

 domen finely and densely punctate. Legs somewhat short and 

 stout. licngtlf 2.2 mm.; width 0.75 mm. 



Florida and Louisiana ( New Orleans, — LaFerte). The single 

 specimen in my cabinet seems to be a male, judging by the ex- 

 posed pygidium ; it has the anterior coxre angulate behind and 

 the corresponding tibiffi not bent but densely clothed with short 

 stitf setse within toward apex, the intermediate trochanters and 

 tibiae not modified, the fifth ventral long, evenly and almost semi- 

 circularly rounded, unmodified on the disk and about three-fourths 

 longer than the fourth. This form of the fifth segment is very 

 different from that of hisjndulus, and in fact throughout the 

 present genus the species, which generally resemble each other 

 very strongly or adhere to a common type of structure, differ 

 strikingly among themselves in the secondary sexual modifica- 

 tions of the male. 



There are several points in the original description of pusiUus, 

 which give rise to grave doubts concerning the identity of the 

 present species. For example, the phrase " les yeux tres-peu 

 saillants," will not accord with this form, nor with any other of 



the genus known to me; also "corselet retre'ci faibleraent 



et progressivement depuis les pommettes, qui sont pen saillantes, 

 jusque'a la base, qui ne parait nullement marginee ; " finally 



" el3' tres presque trois fois aussi larges que le corselet et 



plus de deux fois aussi longues que larges en oval tres-allonge 



posterieurement." The length and width are given as 2.0 and O.fi 

 mm., respectively; that is, if these measures are correct, the in- 

 sect is proportionally much more slender than any other of this 

 pai-t of the genus, and yet the elytra are nearly three times as 

 wide as the prothorax. Either the description is grossly inexact, 

 or the insect of LaFertd is a very remarkable species, quite dif-
